💬Homunculus Infomation

Homunculi are the special companions of Alchemist classes, created to assist their master in battle.

They have their own stats, skills and levels and can evolve after becoming loyal, and mutate to their S form after reaching level 99, gaining new skills and upgrading their level cap to 175.

What is Homunculus and why is it so important?

Homunculus is a special pet that can assist you in many ways: Tanking, Buffing, Dealing damage.
It will decide your play style depend on chosen Homunculus.

💦How to create a Homunculus?

Step 1: Get 1 Embryo (7142) (you can either buy or make 1 through Pharmacy (Prepare Potion))
Step 2: Use Call Homunculus to create a Homunculus consuming 1 Embryo (7142) .
- Got the Homun you want? You're done creating Homunculus.
- Didn't got the Homun you want? Open Homun status table by Alt+R , click Delete, re-do Step 2.

💫How to Evolve my Homunculus?

Step 1: Make your Homunculus Intimacy become Loyal and Level 99.
Step 2: Obtain a Stone of Sage (12040) then use it. Done !
- After Evolution, your Homunculus will get its power significantly increased.

🧡How to make my Homunculus Loyal?

You have 2 ways:

Method 1: Just turn on auto feed and AFK or go farming, Homunculus isn't easy to die as before, so low level area shouldn't be a problem. But the uptime of Homun is only 30 minutes, so make sure to have it called back every 30 minutes.
Method 2: Using Homunculus Supplement (100371) to increase Homunculus's intimacy directly by using it. Each pill gives 10 points of intimacy, so 90 pieces is need to make it Loyal instant from the start.
- Your Homun become Loyal when Intimacy reaches 911 which can be checked by Alt+R and @hominfo
- Note : your Homun Hunger bar won't decrease if it isn't summoned.

Here the table how many Intimacy gained by feeding at specific hunger level :

Hunger	Intimacy
Leave your Homun starving (Hunger bar < 11%)	-1 ( every 200 seconds )
1% ~ 10%	+5
11% ~ 25%	+10
26% ~ 75%	+7.5
76% ~ 90%	-0.05
91%~100%	-0.5

💹Homunculus S

How do I get Homunculus S?

You must be a Genetic.
Your Homunculus must be evolved and have reached level 99. It doesn't necessarily needs to be Loyal, as it will gain its Loyal skill (e.g. Self Destruction, S.B.R. 44, Blood Lust or Mental Charge) once the mutation is completed, regardless of the current Intimacy level.
Go to Lighthalzen (@go 20) and enter the Geneticist Guild building at the 8-9 o'clock area of the map (@navi job3_gen01 45 50).
Inside, talk to Viorel NPC to start a short quest. You can pay a 50k fee to choose which Homunculus S you get or let Viorel decide for you randomly.

Homunculus	Eira	Bayeri	Sera	Dieter	Eleanor
Homunculus
Role	Support	Tank , Magical AoE Damage Dealer	Support , Summoner	Support , Tank	Single Physical Damage Dealer
Food	Small Snow Flower (6098)	Fresh Plant (6112)	Apple Pudding (6108)	Big Scell (6104)	Bun (6115)
Skills and unlocked Level	Eraser Cutter - Level 106 Overed Boost - Level 114 Xeno Slasher - Level 121 Light of Regen - Level 128 Silent Breeze - Level 137	Stahl Horn - Level 105 Goldene Ferse - Level 112 Stein Wand - Level 121 Angriffs Modus - Level 130 Heilige Stange - Level 138	Needle Paralyze - Level 105 Poison Mist - Level 116 Pain Killer - Level 123 Summon Legion - Level 132	Volcanic Ashe - Level 102 Lava Slide - Level 109 Granitic Armor - Level 116 Magma Flow - Level 122 Pyroclastic - Learned 131	Style Change - Level 100 Sonic Claw - Level 100 Silvervein Rush - Level 114 Midnight Frenzy - Level 128 Tinder Breaker - Level 100 C.B.C - Level 112 E.Q.C - Level 133
Which Base Homunculus to choose and why ?	What make Eira special is Overed Boost which gives 190 ASPD and 600 FLEE for both owner and her but drain 50% MaxSP when effect ends. Thanks to those boosted stats, Eira is able to tank a lot of high tiers monsters/bosses. So to maximize her tanking ability, I recommend to choose Amistr as base Homun. Further more, Overed Boost decreases Hunger bar to 1 after ended. So you can spam it to farm Intimacy which is scaled good with S.B.R.44 of Filir and Bio Explosion of Vanilmirth. You can consider either of them as base Homun too.	Bayeri is famous for his tanking ability by abusing Stein Wand and even able to tank ranged monsters by Goldene Ferse which increases FLEE. When reaching level 138, Heilige Stange is now unlocked. It is very low delay , AoE and very strong, the skill damage depends on Homun's VIT. Tips : I highly recommend save up at least 10 Skill Points for Heilige Stange so that you can get it immediately at unlocked level. So I recommend Amistr for High max HP and VIT as Base for Bayeri.	People want Pain Killer the most when picking Sera. It reduces received damage by a Flat amount up to 2000 (capped at 2000) at level 150 `(SkillLevel200)(HomunculusLevel/150)`. Otherwise, Summon Legion is also helpful for tanking. Since she doesn't SP consuming and mainly used for buffing, you may want her to be more useful by choose Vanilmirth for extra brewing chance or Amistr to tank.	Dieter has 2 buffing skills which provide ATK Pyroclastic and resist Granitic Armor. Is main source of damage is Magma Flow which need to be hit to active so i recommend Amistr for Dieter.	Sonic Claw is the thing makes Eleanor , strong, fast but SP consuming. However, her strenght won't change much as her Level increases. And since Eleanor always rush in frontline and draw aggro to her, I recommend Amistr for her survivability , Filir to maximize DPS.
Which Base Homunculus to choose and why ?	Since Vanilmirth's stats is very analogous, so in fact, Vanilmirth is suitable as Base Homun for every Homunculus S. If you're in doubt, then Vanilmirth is a good choice for you. Additionaly, Amistr is also a no-doubt option thanks to the tankiness and VIT bonus buff to help you reach 100 Total VIT without waste precious status points (and legendary Castling skill too).

💨AzzyAI

AzzyAI is an AI for use with the Homunculus systems. It has a huge selection of options, allowing customization of homunculus behavior to suit almost any forseeable circumstance.

Configuration is handled via an easy to use configuration tool.

The AzzyAI application is included in EthernalRO's Full Installer.

💢AI Troubleshooting

Before you attempt any troubleshooting, back up your current AI first:

Open your EthernalRO installation folder and find these folders there:
- AI
- AI_sakray
Copy both those folders to another location outside the EthernalRO installation folder, so you can restore them later if needed.

General

The game client contains two implementations of the AI: the so-called basic (default) AI and the custom (user) AI. The basic one is active by default. That one is generally a stub, which does nothing. To enable the actual AI, you have to switch your game client to load the custom AI. This needs to be done only once at a given game client.

The following are the general steps to verify that you have enabled the custom homunculus AI:

Run EthernalRO as usual.
Check that the Public chat messages are enabled in your chat settings. If not, enable them.
Use the /hoai command ingame and check the message it sends to the chat:
- OK: "Homunculus has been customized." If you see this, your game client is now set up to load the custom AI, move on.
- Not OK: "Homunculus has been activated with the basic AI." If you see this, your game client is now using the basic AI. Use the /hoai command again to switch to the custom AI.
Only after you have verified that your client is set up to load the custom AI: use the @refresh command ingame to reload the AI settings. (@refresh is not an AI command but it reloads the AI files as a side effect).
The custom AI bundled with the EthernalRO client is set to autoattack by default. If you find out that your homunculus does not autoattack, make sure it is not in standby mode:
- Heal your homunculus to full HP.
- Use Warper - Dungeons - Anthell. Normally the homunculus should automatically start attacking the ant eggs near the entrance.
- If the homunculus does not attack, use the Alt+T hotkey to switch between active and standby modes. Do not expect it to switch immediately, allow a few seconds until the homunculus becomes aware of the mode change.

When in doubt, you can restart your game client to troubleshoot the AI. Although the restart is not required to reload the AI, it does not hurt. The /hoai setting is persistent and survives the restart; the standby mode is reset upon restart; homunculus behavior settings are read from the AI files and are not affected by the game client restarts.
